YV 1.6t

'Let no opponent find thee', he says; since the Gandharva Viçvavasu stole the Soma when it was being carried below, he says that, to prevent its being stolen. 'Thou art the good luck of the sacrificer', he says; verily thus the sacrificer grasps the sacrifice, that it be not interrupted. The Soma when bought and tied up indeed approaches the sacrificer in the shape of Varuna [5]. 'Honour to the radiance of Mitra and Varuna', he says, for atonement. They bring forward this Soma, it rests with Agni, they in uniting overpower the sacrificer. Now the consecrated person has for long been holding himself ready for the sacrifice. In that he offers an animal to Agni and Soma, that is a buying-off of himself; therefore of it he should not eat; for as it were it is a buying-off of a man. Or rather they say, 'By Agni and Soma Indra slew Vrtra'. In that he offers an animal to Agni and Soma, it slays hostile things for him; therefore he should eat of it. He honours it with a verse addressed to Varuna; verily he honours it with its own deity.
